IMPROVEMENTJN MACHINES FOR MAKING GUTTERS FOR BUIL-DINGS.

specification forming part of Letters Patent No. 117,255, datcd July 25, 1871.

To all whom it may concern: ported in an in clined frame, S, arranged to slide Be it known that I, ALBION K. P. BUFFUM, of up and down in suitable guides and provided with Gardiner, of the county of Kennebec and State an operative lever, T2, properly applied to it and of Maine, ha-ve invented a new and useful Mathe main frame H and arranged as represented. chine for Making Gutters for Buildings, and I do There extends upward from the frame H, in manhereby declare the same to be fully described in ner as shown, and through the upper girt o of the follo Wing specification and represented in the the frame S, a stationary screw, r, furnished with accompanying drawing, of which a nut, 8, the latter serving as a stop to arrest Figure 1 is a top view; Fig. 2, a rear-end elethe frame S in its upward movement. Another Vation; Fig. 3, a side elevation, and Fig. 4, a cutter-frame, T, applied to a stationary inclined Vertical and longitudinal section ofsuch machine. frame, U, (fixed on the frame H, as represented,) Fig. 5 is a transverse section of a gutter as made So as to be capable of being moved up and down by it. against it, has a screw, V, applied to it and the The nature of my invention consists in the conframe U, such being' so as to change the attitude struction of a machine for making wooden gntters Of the frame T as may be required. The frame for buildings by a combination and arrangement T supports the shaft t of a rotary cutter-stock, of devices in the manner hereinafter more partic- W, which is furnished with cutters u a to form ularly set forth, for subjecting a stick of timber the smfaces D E. (See Fig. 5.) Furthermore, to the operation of a series of rotary cutters and there are rotary cutter-heads, X Y, arranged as planing-tools, which imparts to it the form of a represented, they being fiXed on the upper parts gutter with any desired form or depth of trough of Vertical shafts 11 o, and provided with cutters and of any preferred external configuration, all for dressing the stick, so as to form the sides or as hereinafter described. parts O F, as shown in Fig. 5. In advance of In the dl'awing, H denotes the frame of the these outter-heads X Y there is a horizontal romachine, it being provided with a series, ab cale, .tary cutter-head or cylinder, z, arranged as shown, ofplatforms, arranged in manner and with spaces Its purpose being to dress the stick so as to form between them as represented. There are side the plane surfacesAB. (See Fig.5.) The main ledges or guides, f, arranged on some of such Shaft of the machine is shown at A' as provided platforms,theblank orstickbeingpressed against With a main driving-pulley, B', and also with such ledges while being moved on the platforms. Other or auxiliary pulleys, O' D/ Ef, arranged as It is so forced up to the guides by a series of Set forth. From .the pulley O' an endless belt, pressure-rollers, g h, and an adjustable gauge, i, a', leads to and imparts motion to a pulley, F', o the pressure-rollers being carried bylevers k l, to On a shaft, G', arranged at the rear part of the which Weights or springs are to be applied to frame. Three other pulleys, H' I' K', are fixed cause the rollers to bear the stick laterally. There 011 the shaft G'. From the pulley H' a belt, L', is also an adjustable gauge, m, arranged at the passes to and around a pulley, M', fixed on the front of the machine, and provided with screws Shaft t of the cutter-stock W. So, from the puln n for elevating or depressing it relatively to the ley I' an endless belt, N l passes to and around a bed or platforms of the'machine, Near the, fear pulley fixed on the shaftp of the cutter-stock R; end of the frame is a feed-roller, I, and over such and from the pulley K1 a belt, K2, extends to and roller is a feed-and-pressure roller, K, the latter gives motion to a pulley, L2, fixed on a shaft, M2, having its shaft 0 supported byavibratory frame, arran ged at the front end of the frame H. The L, provided with a hand-lever, M, for elevating` shaftM.2 carries two pulleys, N 2 0/, from which and depressing the said frame. In advance of belts P' Q' R' proceed to pulleys on the shafts of the roller K is another such roller, N, arranged the outter-cylinder Z and rotary cutter-heads X in a vibratory frame, O, provided with a hand- Y. There is a wheel, S',fixed on the shaft of the lever, P, for effecting the Vertical movements of upper feed-roller, the periphery of the said wheel such frame. In front of the said roller K is a resting against that of an elastic roller or pulley, rotary cutter-stock, R, provided with 'cutters of, T/, fixed on a shaft, U', provided wi th a drivingfor forming the hollow G (see Fig. 5) of the gutpulley, V', from which a belt, VV', extends to the ter. The shaft p of the said cutter-stock is suppulleyDI on the main driving-shaft A'. A crossed p being given in Fig. 5.

` reduce it to the form required.

In using the machine, the front end of the stock to be reduced is to be entered between the feedrollers, by which it Will be seized, the stick being advanced or impelled through the machine by their action upon it. In going through the said machinethe stick will be formed and grooved to the shape required, a transverse section of it The cutter-cylinder for forming the hollow G can be brought into action on the stick imm ediately after the front en d of it may have passed by the cylinder, and just previous to the passage of the rear end of the stick by the said cutter-cylinder it may be depressed out of action on the stick, the same causing the groove of the gutter to be formed With stopped ends. The said groove may be plowed to any desirable depth and may be made deeper in one part than another, as occasion may require, to impart to it the proper slant or inclinations.

I make no claim to the mere combination of a bed, feed-and-pressure rollers, lateral guides, and a cutter-cylinder, as used in common planingmachines for planing a board or in machines for making a molding. i

/Vhat I claim as my invention isrl`he gutter-machine hereinbefore described, the same consisting of the series of platforms a b c d 6, the guide f, the pressure-rollers g h, adjustable gauge m, the feed-and-pressure rollers I K N, the rotary cutter-stock R With its adiustable frame S, rotary cutter-stock VV with its adjustable frame T, the cutter-heads X Y, and the cylinder Z, all the cutter-heads or cylinders being v provided With cutters, and the whole being constructed and combined together and applied to the frame H, substantially in manner and so as to operate as and for the purpose specified.
